Question

five x upon four + two upon three = one upon five​

Answer 1

$Answer:$ $x=-{\frac{28}{75}}$

$\frac{5x}{4}+\frac{2}{3}=\frac{1}{5}$

$\left \{ {{\frac{2}{3}-\frac{2}{3}} \atop {{\frac{1}{5}-{\frac{2}{3}}} \right.= \left \{ {{} \atop -{{\frac{7}{15}}} \right.$

${\frac{5x}{4}=-{\frac{7}{15}$

$4*{\frac{5x}{4}=4(-{\frac{7}{15})$$=5x=-{\frac{28}{15}$

$\left \{ {{5x/5} \atop {-{\frac{28}{15}}/5=-{\frac{28}{75}}$

Hence, the final answer -28/75. I hope this helps you. Good luck solving, mathematician!
